I had a bash at Silvermere with a 915 D3 and a 915 Fd 3wood, both in the Diamana shaft. I currently have a 910 D3 with a full RIP shaft, so a comparison between a 910 and 915 is something I was looking foward to.
My immediate impression on first hit is the sound. The 910 has a crunching sound whereas the 915 has a loud crack, more inline with TM. Tbh, I didn't like it, with sound reflecting the firmness of the face, but this was in a bay environment so outside the sound should dissipate.
The stock shaft didn't too much for me either, felt a bit unresponsive with the hard face, so in order to compare Titleist heads, I cheekily used my SureFit tool and popped the 915 head on my specific shaft. The feel was a bit better but the face still comes with crack and feels hard. The launch certainly looked lower, yet without LM details, I can't confirm. It may infer from this that I wasn't enamoured with the driver. A little bit, yes, but I'd like to pursue further via an official fit.
The fairway wood was a different kettle of fish. Lovely sound and great performance, even with the stock shaft. It's long off the tee and fabulous off the deck. Can't wait to get hold off this using a LM, decent balls and a different proper shaft.
Can't wait to try the Nike Vapor Pro and Mizuno drivers!
